T all whom it may concern: Be it known that I, J HN MURRAY, a citizen ofthe United States, residing at Tacoma, in the county of Pierce andStateof Washingto'n, have invented a certain new and usefu Improvement inSaw-Guards with Dimansion Ga e Attachments for- Shingle- Cli pers; an Ido hereb declare that the I to owing is a true and in 1, clear, andexact account or descri tion of the invention, such as will enable ot erpersons skilled in the -,,business to which it appertains tosuccessfully make and use the same.

My invention relates to improvements in saw ards with dimensionattachments, and has or its object a uard so constructed and related tothe mac ine that it will greatly lessen, if not entirely prevent thedanger of persons becoming injured by contact with the movable arts ofthe machine.

With the above and other obj cats in view my invention further consistsin the novel details of construction and combination of parts to befully-hereinafter described andater pointed out in the claims.

In the drawings:Figure 1 is a view in perspective of a shingle trimmingmachine equipped with my improvedguard. Fig. 2

' is a perspective view of a guard and dimension attachment iii-detachedrelation to the 1 lmachine. Fi 3 is a like fragmentary view of a portion01 one end of the guard. Fig. 4 is a similar view of the portion of'theopposite end of the guard; and Fig. 5, is a perspecparts ofthe dimensionattachments. I v

. 1 designates the fiooron which the shingle trimming machine Zyisfts;3, the wall; 4, a led e; and 5, a raised portion of the floor.

'40 he guard consists of a member 6, formed of a strip of materialhaving an intermediate portion mclinedupwardl as at 7, from whichinclined part. the mem er continues in .a

major straight ortion as'at 8, the end of the latter being inc ineddownward as at 9., 1'0

denotes a second member of which the guard is composed consisting of astraight major portion and an upwardly inclined inner end 11, slotted at12, and adjustably secured to no end. 9, of member 6, by means of theset screws 13. 7

As shown in Fig. 1, members 6 and 10 at their outer ends aresecured tothe bed of the machine as st le and 15, in such position,

that the several members in their assembled position will overlie thesaw 16. 17, desig- Speeificetion of Letters Patent,

Applicationflled November 9, 1905. "Serial No. 286,584.

nates a guard member formed of a section of flat metal which is formedwith aright angular lip 18, having threaded perforations to receivescrews .19 which extend through inclined portions 7 and by means ofwhich member 17, is removably held. to portion 7. The member 17 performsthe function of preventing contact of'the operators hand with the movingsaw when grasping the shingles after the sawing operatmn. Y

In conjunction with m guard I employ a dimension attachment whichcomprises two members, each consisting of a fiat bar 20, attached at 21,to straight portion 8, so as to project at right angles therefrom asshown.

he outer ends of bars 20, are longitudinally slotted as at 22 andadjustably carry members 23 vconsistin of a right angular element whichis engage by a set screw 24, which normally passes through slot 22. Itwill thus be seen that members 23 may be adjusted towards or away fromthe saw to var the width of the shingles since the latter 1s determinedby the distance :ex'isting between the saw 16 and the dependin part ofmember 23. It will be further noter tnat by adjustment of screws 13,-the distance between portion 8 of the guard and the uppermost part ofthe saw l6,.may be regulated as desired. As each side of the machine isequipped with a guard, I preferably brace the two by the employment ofthe bar 25 which extends transverse of the machine and is secured at itsends b screws 26, to the portion 8, thereby provi ing mutual sdipportand adding rigidit to the several guar s.

Having thus in y described my invention, what I claim as new and desireto secure by Letters Patent, is Y 1. A guard for shingle machinescomprising in combination with arshingle machine,

amember having two straight portions, a

connecting inclined portion between said straight. portions, and adownwardly extending end, one end of said member being socured to themachine bed, a second member having one and secured to the machine bedand havin its opposite end extendin upwardly'an adjustably secured tosaid ownwardly extending end of the first member, and a third memberhaving a right annular lip secured to said inclined portion oi the firstmember to extend downwardly on one side of the saw.

2. A guard and dimension attachment for shingle trimming machinescomprising in combination With a shingle trimming machine, a pair ofmembers each connected adjacent oneof its ends to the machine bed, anadjustable connection between said members and gage members secured tosaid guard andcomposed of projecting bars and right angular members adustably connected to said bars;

3, A guard for rotary saws consisting of a member having a horizontalend and an in; clinedend, a second member having a horizontal end, aninclined intermediate portion, and a downwardly extending end ad ustablysecured to said inclined end of the first member.

l. A guard for rotary saws consisting of a some"! member llavingtwostraight portions, a connecting inclined portion between said strai htportions and a downwardly extending em a second member having an nwardly extending end nd.justably secure to said downtwo subscribingwitnesses. i JOHN MURRAY.
